Introduction to Multilines Sacramento City College Engineering Design Technology Introduction to Multilines
Drawing Multilines • A multiline consists of between 1 and 16 parallel lines that act as one line. • The lines in the set of multilines are called elements. Introduction to Multilines
Drawing Multilines • Multilines are commonly used for drawing • Roads • Walls of buildings for architectural plans. Introduction to Multilines
Drawing Multilines • The MLINE command is accessed by: • Picking the Multiline button from the Draw toolbar • OR • Picking Multiline in the Draw pull-down menu • OR • Typing ML or MLINE at the Command: prompt. Introduction to Multilines
Drawing Multilines • Three commands relate to multilines: • MLINE. (ML) • MLSTYLE. • MLEDIT. Introduction to Multilines
Drawing Multilines • The MLSTYLE command • Allows you to create multilines. Introduction to Multilines
Drawing Multilines • The default multi-line style has: • Two elements (lines). • Continuous line type. • Is called STANDARD. Introduction to Multilines
Multiline Justification • Justification determines how the resulting lines are offset. Introduction to Multilines
Multiline Justification • Justification • Can be specified only once during a single MLINE command sequence and • Is based on a counterclockwise rotation direction. Introduction to Multilines
Multiline Justification • The justification options are • Top • Zero • Bottom • TOP is the default • The current value remains in effect until changed. Introduction to Multilines
Top Justification Introduction to Multilines
Zero Justification Introduction to Multilines
Bottom Justification Introduction to Multilines
Multiline Justification • To change the justification • Enter J at the first prompt • Enter the first letter of the desired justification • Top • Zero • Bottom Introduction to Multilines
Multiline Justification • The justification setting is stored in the AutoCAD CMLJUST system variable. Introduction to Multilines
Adjusting the Multiline Scale • The Scale option controls the multiplier for the offset values specified in the MLSTYLE command. • The multiplier is stored in the CMLSCALE system variable. Introduction to Multilines
Adjusting the Multiline Scale • When the scale is 1, the distance between multiline elements is equal to 1 times the offset distance. • If the offset distance is 0.5, the distance between multiline elements is 0.5 when the multiline scale is 1. • If the multiline scale is 2, the distance between multiline elements is 1 (0.5 x 2). Introduction to Multilines
Adjusting the Multiline Scale • For zero justification, • The multiline elements are offset 0.5 units on either side of the definition points picked. • Example: If the multiline scale is 2 • Top and Bottom justification = 2 units offset • Zero justification = 1 unit and -1 unit offset. Introduction to Multilines
Setting Your Own Multiline Style • ML Command Style option • Allows you to specify the current multiline style. • The style must be saved before it can be accessed. Introduction to Multilines
Setting Your Own Multiline Style • Using saved Multiline styles • Type: ML • Type: ST - to access the style option, • Type the known multiline style name. • A “?” lists all of the names of the multiline styles. • Typing a name of a multiline style that does not exist, the Load multiline style from file dialog box is displayed Introduction to Multilines
Setting Your Own Multiline Style • Multilines are stored in the acad.mlnfile library. Introduction to Multilines
Setting Your Own Multiline Style • You can load the multiline style from another file (not acad.lin). • Custom multilines can be purchased for AutoCAD. Introduction to Multilines
Defining Multilines Introduction to Multilines
Multiline Styles • Use the MLSTYLE command to define multilines. Introduction to Multilines
Multiline Styles • The MLSTYLE command can be accessed by: • Picking the Multiline Style entry in the Format pull-down menu • OR • Typing MLSTYLE at the Command: prompt. Introduction to Multilines
Multiline Styles • The Multiline options are: • Current: • Name: • Description: • Load... Button: • Save... button. • Add button. • Rename button. Introduction to Multilines
Multiline Styles • Current: Text box. • The Current: text box makes the specified multiline style current. • Specifying a different style changes the setting of the CMLSTYLE system variable. • Until you create a multiline style, the only style available is STANDARD. Introduction to Multilines
Multiline Styles • Name:Text box. • This text box is used to enter the name for a new style. • Description: Text box. • An optional description of your multiline style may be entered in this text box. Introduction to Multilines
Multiline Styles • Load... button. • This button allows you to load a multiline style from an external multiline definition file. • Save... button. • The Save... button is used to save a style to a file. Introduction to Multilines
Multiline Styles • Add button. • Pick the Add button after entering a multiline style name in the Name: text box. • This adds the multiline style name to the list of defined styles. • Rename button. • Pick this button to rename a multiline style. Introduction to Multilines
Creating A Multiline Introduction to Multilines
Element Properties Dialog Box • Create a new multiline style by • 1. MLStyle • 2. Type name of new multiline • “NewExample” • 3. Click ADD Introduction to Multilines
Multiline Element Properties Introduction to Multilines
Element Properties Dialog Box • Elements Properties Dialog Box contains: • Elements: area. • Add button. • Delete button. • Offset text box. • Color... button. • Linetype... button. Introduction to Multilines
Element Properties Dialog Box • Elements: area. • Displays the current: • Offset. • Color • Linetype settings • for each multiline element. • Picking one of the elements highlights the items for modification. Introduction to Multilines
Element Properties Dialog Box • Add button. • Add a new element to the multiline definition. • Delete button. • Deletes a highlighted item in the Elements: area. Introduction to Multilines
Element Properties Dialog Box • Offset text box. • Enter either a positive or negative offset value for a highlighted element. Introduction to Multilines
Element Properties Dialog Box • Color... button. • Accesses the Select Color dialog box. • Pick the color you wish to assign to the highlighted element. • After picking OK, the new color is displayed in the image tile next to the Color... button. Introduction to Multilines
